01 - Preheat oven to 425°F. Line a baking sheet with parchment paper and set aside.
02 - Steam or boil the peeled and cubed sweet potatoes until fork-tender, about 10–12 minutes. Drain thoroughly and mash until completely smooth.
03 - In a large mixing bowl, combine the mashed sweet potato, egg, almond flour, Parmesan cheese, garlic powder, salt, and black pepper. Stir until the mixture is uniform and well combined.
04 - Spread the sweet potato mixture onto the prepared baking sheet, forming a 12-inch round approximately 1/4 to 1/2 inch thick. Smooth the surface evenly.
05 - Bake the crust for 20–22 minutes until firm and lightly golden on the edges.
06 - While the crust bakes, combine the honey, chili flakes or hot sauce, and apple cider vinegar in a small saucepan. Gently warm over low heat for 2–3 minutes, stirring occasionally. Remove from heat and set aside.
07 - Remove the baked crust from the oven. Spread the marinara sauce evenly over the surface. Sprinkle with mozzarella cheese, then layer the pepperoni slices on top. Scatter the sliced red onion and bell pepper over the cheese if desired.
08 - Return the pizza to the oven and bake for an additional 8–10 minutes until the cheese is melted and bubbly and the edges are crisp.
09 - Drizzle the prepared hot honey generously over the finished pizza. Garnish with fresh basil leaves and additional crushed red pepper flakes. Slice into wedges and serve immediately.
